PAC is a multivalent electrolyte that significantly reduces the colloidal charge of suspended impurities in water. Because of large molecular weight, strong adsorption capacity and excellent coagulation capacity, the formed flocculating constituent is larger, and the coagulation sedimentation property is better than that of other flocculating agents. The substance has high polymerization degree, short time for forming flocculating constituent, small influence of water temperature and small influence on the pH value of water. The pH value is suitably in the range of 5 to 9. Polyacrylamide (PAM) is a high polymer, has the characteristics of high coagulation speed, small dosage, large and tough flocculating particles and the like, is used together with PAC, and aims to utilize the neutralization effect of an inorganic flocculating agent on colloid particle charges and the excellent flocculation effect of a polymeric flocculating agent to achieve better treatment effect.

The air floatation tank is connected with a dissolved air tank. The air floatation tank is a shallow air floatation device. The used shallow air floating device is a JM-Q type high-efficiency shallow air floating device produced by Hongjin water treatment equipment limited company in Yixing city. Dissolved air tanks are also produced by the company.
